Success is a journey, not a destination.

No one starts out on top. You have to work your way up.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Do what you have always done and you will always be what you have always been

Don't fear failure, fear being in the same exact same place next year as you are now.

There are no bad mistakes in maths, only discoveries.

The master has failed more times than the beginner has even tried

We are all maths people : step 1 - do maths and step 2 - be a person. 

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

A book a day keeps the stupidity away.

Lose an hour in the morning and you will spend all day looking for it.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

He who has begun his task is half-way done. Have the courage to begin!

Pure mathematics is in its way, the poetry of logical ideas.
